I do not have the item any more.
GRRRRRRRRRRRR . . . . .RRRRRRRRRR . . . . . . RRRRRRRR !!!!!!
WHASSAMATTAH YOU !
Any intelligent person or packaratama extremus . . .would have kept that unit for its discrete parts !
BOARDS FIRST SIDE
On photo 1, the presence of X1 looks as being a 32,768 kc or ? freq crystal . . . . so it should be associated with some degree of sophisticated associative circuitry . . .eg . . . .a microchip on the board and the only space available seems to be in the area under the yellow wrapped battery / cell.
Expected microchip being used . . . . with black epoxy conformal coating . . . .Chip On Board

On other parts,the white D1 is suggestive of a diode set but only being on one board side and not resembling the casing used on any that I have ever seen.
The gray cased YUSAN R1 SW-200 R1 certainly looks too large to be a resistor associated with circuitry powered with that pip squeak cells capability.
NOTE that the one lead visible, of its two, is being . . . .GOLD FLASHED.
I have seen that done on reed switches . . . . . also, this doesn't resemble a ball switch . . as .suggested by others, with it having separate axial leads . . .instead of using radial leads, mounted on only one end.
Also, it seems that half of it is resting down in a channel in a WHITE plastic block . . .I wanted more info on that !
The only other info is the BT1 . . . .which is B
. . .part designation .
THE BOARDS OTHER SIDE . . . .
Looks like this products development time was back in 11-13-2006.
Looking at that WHITE plastic block, is it loose fitting enough to slide up and down the GRAY YUSHIN portion, and is there a rod / bar magnet molded within the white block ?
Just above the marked T7-T6-T9 test points seems to be an exposed push button switch, excluding its very top contact disc. One outer ring and a concentric inner ring and then ? ? ? for the treatment of the innermost rectangular area and 3 contact(s).
Then there is only the cell and its tri -pin peripheral solder pins and the single other battery contact solder pin near T5.
Looks like final insulative / protective black epoxy blobs were placed on all 4 pins after soldered in.
Pulling the cell by de soldering those 4 pins would be in order to be able to see what is mounted under the battery /cell.
BUT . . . .only 6 cross board inter-connective vias are being seen, and with use of QUITE hefty traces and which is NOT conducive to being C.O.B. connections (small / fine ).
And finally there is all of the white contamination on part of the board, and I'm not immediately blaming the SPACED APART cell for all of that leakage .
NOW I DONES GONNA TELLS YOU . . . .
Most LIKELY . . . .
This could have even been a mini flashlight, for finding keyholes at night with its missing lamp / LED connected at the T9 area, using the press or slide activated reed switch as mentioned.
Any other application would qualify use of a replaceable or rechargeable battery with timely exchange.
This unit . . . . a light that gets infrequent 15 second uses . . . .ergo one shot battery . . . . throw away unit . . . .99 cent store.
( Excluding . . . . .WHY the mounted X1 ? ? ? ? ? xtal. )
WHAT SAY YE ?
Thaaaaaaaaaaaaaasit . . .
